It's worth a read to have your mind blown about what you can do when you hand optimise assembly.

Great reads! Thanks for posting.

I think it would be neat if, as something gained popularity, more and more of it were re-written in optimized assembly. I mainly work in .NET, which performs fine for what it is, but there are some libraries like Dapper (which is a micro-ORM) which are written in IL, which is incredibly difficult to do but results in it being insanely fast compared to what you could do in purely managed .NET. I'm sure if it were written in assembly it would be an order of magnitude faster than that.
